TYPES OF ONLINE CASINOS
There are a number of types of online casinos at which you can play. Many of them are Java-based and load directly in your browser. Some of them use Flash or Shockwave, which also runs in your browser but may require the Flash (or Shockwave) plug-ins available from Macromedia.
Both of these types are usually referred to as no-download casinos, even though you have to download graphics and sounds every time you play. The biggest advantage of a no-download casino is that it can be played on most computers and operating systems, and many of these will also work on WebTV.
Then there are the downloadable software casinos, which will only run on Windows-based platforms. File sizes generally range from 5-15 megabytes, so you should make sure you are definitely planning to play at this casino before investing the time to download. If you run Windows, I recommend that you stick to these download casinos. They are generally more stable and secure, and once downloaded minimize communications between your computer and the casino game server, making them ideal for those of you with dial-up connections.
